a buddy of mine has a kicker L7 solobaric 12 and a jl 500.1 amp. ive listened to it and it just doesnt seem to sound as good as it should. i knwo all about hooking up and stuff, but not too knowledgeble on the tunning part. could someone let me know how i could tune this out right and possible some specs on a box that would bring out the true potential of this set up

 

Well.. what sounds wrong with it?

 

How big is the size of the enclosure. If it is too small it will raise the f3 (limit low bass) and make it sound like a PA speaker. Also check the Ohm load if the L7 is a DVC sub perhaps it is wired in series instead of parallel thus raiseing the load from 2ohm to 8 ohm making the system less effecient. Is the box ported, sealed or band pass?
